The wiimote has an internal accelerometer which can report data to the host. Userspace may now write to a new sysfs file to make the driver enable accelerometer reporting. This is not enabled by default to reduce power consumption of the wiimote. Accelerometer data is reported every few milliseconds and thus consumes much bluetooth bandwidth which costs much energy of the wiimote. By writing 0 to the sysfs file, accelerometer reporting is disabled again.
This is an odd interface. Why can't you request the accelerometer data when a device file dedicated to the accelerometer is opened?
